4 Introducing NJ-GeoWeb The Bureau of Geographic Information Systems (BGIS) has developed NJ-GeoWeb, a data and feature-rich GIS application for users of the Internet. NJ-GeoWeb enables the combining of many environmental map layers into a single integrated map. Map tools and searches allow users to interact with the map and the environmental data layers. The GeoWeb profile was developed to suit the needs of a general audience that may be interested in viewing environmental information related to features that exist near a location or area of interest. The GeoWeb profile allows users to view and interact with a very diverse set of environmental map layers and related data. Users may execute searches to find a location or area of interest, display features from the mapped data layers, and view environmental data associated with those features. Additional tools are provided to allow users to select and buffer features, measure distances and calculate areas, and determine or locate and display NJ state plane coordinates. Additional NJDEP Program profiles within NJ-GeoWeb have been developed to address the needs of specific user communities. The developers of the NJ-GeoWeb application have worked with staff from NJDEP programs to determine the GIS layers included within each profile. Regardless of the profile initially selected by the user at the application s launch, the GeoWeb profile is always available to the user, and the user may switch between these two profiles by clicking on one or the other profile s tab. When switching between profiles, the spatial extent of the map is maintained, but the GIS layers made available to the user changes. To access a different profile, a user may return to the splash page, and click the desired profile. The other available NJDEP Program profiles include: Ambient Water Monitoring Bear Energy and Sustainability Geology Historic Preservation Safe Drinking Water (SDW) Site Remediation Program Tidelands Water Allocation Well Drillers Searches: NJ-GeoWeb includes custom searches, most of which are associated with a particular map layer. The availability of a particular search in any NJ-GeoWeb profile is dictated by whether its subject layer has been made available in the current profile. If the profile includes the layer, the search associated with it is listed under the Searches link for that profile. Reports: For a few layers, a selected set of map features from those layers (e.g., the NJEMS Sites layer) can be passed to DEP Data Miner reports through a document link. Some layers are also linked to Business Objects reports via document links. If an NJDEP program has developed custom DEP Data Miner or Business Objects reports, those reports may be able to accept a selection set from NJ-GeoWeb and display additional environmental data associated pg. 2

5 with the features displayed in NJ-GeoWeb. The purpose of this tutorial is to enable users to become familiar with capabilities and functionality of NJ-GeoWeb. NJDEP s Bureau of GIS plans to make further customizations to improve the user experience and add functionality to make NJ-GeoWeb an even more powerful and useful tool for NJDEP staff and the public. NJ-GeoWeb Interface The application s user interface consists of a Map View Frame, a Maps Profile dropdown, a Searches dropdown, a Map Tools toolbar, a More Tools menu, the Map Content frame and a Navigation Bar. By default, the Map Content frame is open when the application is launched. Many of the tools when executed launch windows that can be moved and placed anywhere on the application window. When finished using a tool, the user can close its window. Figure 1: NJ-GeoWeb Functionality Near the upper-left of the screen there is a tab for the Home page, a dropdown for Map profiles and a dropdown for a list of Searches available in NJ-GeoWeb. Here we have launched the GeoWeb Profile. Click on the Searches and Maps dropdown arrow to view the list of searches and Profiles available in the NJ-GeoWeb application. pg. 3

6 Map View Frame The Map View Frame displays the main map, and is the major focus of the application. This is the area where map layers are displayed at different zoom levels (or scales) and where the user can pan, zoom in, and zoom out, to areas of interest. When using the GeoWeb profile, the opening of the application displays New Jersey with county boundaries along with the Mid-Atlantic States layer. The Map View frame also displays the Navigation Bar, the North Arrow and the Scale Bar. On the left side of the display, below the map, the current map s scale is displayed. In the lower right corner is the view coordinates tool. This displays the mouse cursor s current X and Y coordinates (in NJ State Plane Feet). Clicking on the Overview Map button brings up a small map of New Jersey with a box indicating the current map window location. Figure 2: Map View Frame Navigation Bar Figure 3: Navigation Bar The Navigation Bar can be used to Zoom In, Zoom Out and Zoom to the Full Scale of the map by clicking on the globe in the middle of the Navigation wheel. pg. 4

7 Map Content Window The Map Content window enables the turning on and off of mapped layers, and is a floating control that can be moved to any location on the display or closed and re-opened by clicking on the Map Content button. Layers are organized into groups that can be expanded to show what layers they contain (click on the double arrow symbol next to the group). Layers are grouped in commonly recognized categories, as shown in Figure 4. Figure 4: Features of the Map Content Window Layers are turned on by clicking the checkbox next to the layer name. Another click in the checkbox will turn a layer off. Layer names that appear grayed-out are not visible at the current map scale. Placing the mouse cursor over a grayed-out layer name and holding it still for a few seconds will activate a mouse-over popup that indicates the scale range at which the layer can be viewed. Layers higher in the stack will draw on top of those that are below. Right clicking on a layer name launches a layer menu through which a user can make the layer active for selection and identification purposes, zoom to the layer s extent, zoom to the scale at which the layer becomes visible, or view the layer s metadata. pg. 5

View or Hide coordinates of the cursor s location. Opens the legend which displays the symbols of currently visible layers Opens the Print tool for creating basic map print layout Opens the Change Active Layers window that allows the user to select a different active layer whose features can then be identified or selected. Clears all buffer rings drawn on the map using the buffer selections and any of the Radial Search tools Drop down containing a selection of more tools Allows the user to select a feature or group of features on the map. There are several methods of selecting objects, such as by point or by line. The user can also draw a rectangle, circle, or irregular polygon in order to select objects. Once this is done, a buffer can be drawn about the selection and a menu will display all of the selected objects. Allows a user to draw graphics and labels on the map. Graphics include: point, line, polyline, polygon, circle, and rectangle. Allows a user to measure a point (get the coordinate), measure a distance between two or more points, or measure the area and perimeter of an irregular polygon, circle, or rectangle. Allows a user to buffer around already selected features (buffer active selections), or buffer around any location (point) clicked on the map. Either method provides a way for users to select features from a target layer that fall pg. 6

9 within the user entered buffer distance. Locate Point Using Coordinates Set Scale Add Local Data Clear Local Data Clear Map Metadata Allows a user to locate and zoom to the location of an entered x,y coordinate in the New Jersey State Plane Coordinate System (NJSPCS), Latitude/Longitude, or UTM. Allows the user to zoom to a user specified map scale. Adds a map data file to the currently displayed map. You have these options:esri Shape file, KML, WMS, GPX Removes local map data you have added to the currently displayed map. You cannot add more than one local file to the map viewer at a time. You must remove any currently added file before being able to add another. Allows a user to reset their map extent, clearing all results, selections, and graphics to the original map extent. Reference information about the map that has been made available, including creation date, quality estimates, the projection and coordinate systems used, copyright and other details. NOTE: The function of each tool on the tool bars in NJ-GeoWeb can be revealed by holding the mouse cursor over the tool s icon. When in doubt as to the name or function of a tool, use this feature. More Tools Figure 6: More Tools Control More tools include some additional common GIS functions. The More Tools frame can be moved or closed. When one of the tools is clicked, a new window will open for that particular tool. The tools in the Map Tools toolbar are common to all profiles. The tools within the More Tools frame will vary slightly depending on the current profile the user is working in. There are some custom tools created for specific layers available within certain profiles. If the layer exists within the profile, the associated tool will be available within the More Tools frame. An example of this is found in the Historic Preservation profile that has a Cultural Resources Radial Search tool that is not available in other profiles. The common More Tools are Selection, Mark Up, Measure, Buffer Selections, and Locate Point Using Coordinates. The tool windows for each of these are shown and described in Figure 7. Figure 7: More Tools Descriptions pg. 7

10 Selection Tool Used to select features from the currently active layer. When features are selected, they are highlighted on the map and are listed in the Results table. The Results table tracks both selections that are current and those that had been completed during a previous selection process or search. Selections can be saved and previously saved selections can be retrieved. Mark Up Tool Used to draw graphics (points, lines, shapes) or add labels to the map. Mark ups are maintained in a Results table and like selections can be saved and later retrieved. Measure Tool Used to measure a distance, an area or a point location in NJ State Plane coordinates. Distance can be measured by either clicking on Measure Distance to find the length of one line, or by clicking on Multi Segment, which allows the user to determine the distance along a line made up of multiple points. Measure Polygon provides both perimeter and area. Measurements can also be added to the map display (Add to map) as a graphics and be added to the Results table or saved and retrieved at a later time. Buffer Selections Tool Used to create a buffer selection, buffering around features from the active selection list, from a point on a map, or an entered coordinate, with a user supplied radius distance. The resulting selections from the buffer operation listed within the Results list. pg. 8

11 Locate Point Using Coordinates Tool Allows for the user to input x and y coordinates in order to find a specific point. The coordinates can be in NJ State Plane, Latitude Longitude, or UTM coordinate systems. This function is most useful if the coordinates of the point are already known and the user wants to search for the location. Searches There are several searches in NJ-GeoWeb for finding general locations of interest, There are also searches that locate features that are more NJDEP program focused. Searches can be accessed by mousing over the "Searches" button toward the upper left corner of the application's window. Users can find a general location of interest by street address, county, municipality, place, ZIP code, parcels by block and lot, watershed management area, or watershed/sub-watershed. There are additional searches that are more specific to data within different profiles, and additional searches will be added in the future as NJ-GeoWeb is further developed. Figure 8: NJ-GeoWeb Search Feature showing the Parcels by Block/Lot search 1 2 pg. 9

12 Linking to DEP Reports Features from the NJEMS Sites GIS layer are linked to DEP Data Miner via their NJEMS Site ID. This allows easy access to DEP activity, permitting, and enforcement data from a limited number of existing DEP Data Miner reports. To access these reports, click on the document link at the bottom of the More Information window. The More Information window is opened when the user uses the Identify Tool on a feature from the NJEMS Sites layer. The More Information window also opens when the user clicks on the label index (blue underlined numbers) for a feature in the Results window produced as a result of a search. As shown in Figure 9, the search yielded a number of sites that matched the search criteria. Clicking the hyperlinked number next to the selections in the Results window opens the More Information window that displays attribute data for the corresponding feature. pg. 10

13 Figure 9: More Information about Selected Sites Click the Link to Access More Information About the Facility Additional data is accessible by clicking the Documents link (Figure 10), which exposes the link to access Data Miner reports. Figure 10: Data Miner Link in More Information window Data Miner Link pg. 11

14 A great deal of information is available through the link to DEP Data Miner, including permit, inspection, violation and enforcement activities, searchable by date ranges (Figure 11). Figure 11: Data Miner Window Certain layers have special reports associated with them. These reports display additional data associated with the feature on the map. This data is derived from NJDEP s enterprise environmental databases (e.g., NJEMS, COMPASS) and displayed via pre-formatted Webbased reports. The reports can be accessed via the Reports tab in the More Information window or the More Reports drop down in the Results table after the feature has been Selected using either the Selection tool or as a result of a Search process. pg. 12

16 More Tools in the Results Window Additional tools are available once a selection has been made and a selection list is displayed in the Results table. When the More Tools button is clicked, a new window appears with these extra tools (see Figure 14). Figure 14: Click for More Tools in the Results Window The buttons on this window enable additional functions related to the current selection list such as turning off and on the selection list, deleting the entire list, turning on or off the index numbers that identify listed items on the map, etc. This is also where a current selection list can be saved, or to another user. The buttons and their related functions are detailed in Figure 15. Figure 15: Results Table Tools Toggle Selection Toggles off/on the active selection in the Results Window. Deletes the currently selected features from the Results table. Remove selected Toggle Indexing Toggles off/on the index numbers on the map that identify selected items from the Results table. pg. 14

17 Save selections Zoom to all Zoom to Feature Clear buffer rings Document viewer Opens a new window where selections can be named and saved, and be made private or made public for others to view. Once a selection is saved it can be e- mailed to others. Zooms the map display to show all the selections from the list. Zooms the map to display only the selections that are active (checked in the Results table window). Clears buffer rings if they are displayed on the map (that were created using the buffer tool on the More Tools window) Opens the Document Viewer window which lists documents linked to the selected records. Clicking on the links opens the document in a new window The ability to save a selection set can be very useful for keeping track of successful searches, or for sharing information with others via . Use this feature after a successful search returns a selection set that you want to keep for future access. Saved selections will be available for 30 days before being cleaned off the NJ-GeoWeb server. pg. 15

18 Printing the Map NJ-GeoWeb provides a Print Tool in the Map Tools toolbar. There are three print templates. First is the "Simple Map" template. Second is the "Map with Selections" template, which includes a map with information for selected features. Third is the Easy Print template which allows the user to customize the map layout by using options for page size, including an overview map, legend, and selection results. These map layout elements can appear all on the same page or be forced to print on separate pages from the main map. All three templates provide the option for landscape or portrait orientation, and the option of generating an HTML page or a PDF (Adobe Reader required). Figure 16: Print Tool You also have the option to retain the existing scale of the map. The user can enter a title and sub-title for the map, along with any comments. If the user has map features selected but chooses the "Simple Map" template, the selections will be labeled but not identified on the map. If the user instead chooses the "Web Print" template, the map layout will label the features on the map and include a section of the page for identifying the labels. The map page window is generated by clicking the "Print" button. If HTML was selected as the output format, use the browser window's print function to send the map to a printer. If PDF was selected, use the print function within Adobe Reader to send the map to the printer. Also, there is a Print button at the bottom of the More Information window (which opens when the Identify tool is used) that when clicked on, launches the Print tool that allows the printing of the map with the attribute data in the More Information window. pg. 16

20 Tutorials The following series of scripts walk users through most of the significant functionality that exists in NJ-GeoWeb. There are some additional tools and functionality that have not been highlighted in these tutorials. Feel free to deviate from these tutorials to explore on your own. It is usually best to quit out of NJ-GeoWeb before starting a new tutorial. Note: NJ-GeoWeb runs best in Internet Explorer, Chrome, and Firefox web browsers. NJ-GeoWeb Tutorial 1: Environmental Investigation 1. Launch NJ-GeoWeb by going to the internet website: Click on the button. 2. Mouse-over the Searches dropdown near the upper-left corner. Use the Address Search to search for an address you know exists in NJ. If you live in New Jersey, your home address would be fine. Enter the Street address and ZIP Code. Click on the Search button. If the address is found the map will plot a red cross symbol at the approximate pg. 18

21 location of the address, and place the address record in the Results window. NJDEP Building example: Street: 401 E. State St., ZIP: If the 2015 aerial photo is not appearing on the map, go to the Map Content window (on left hand side), turn on the 2015 Imagery (Natural) map layer (toward the bottom) by clicking on its checkbox. This will turn on the aerial photo. 4. In the lower left corner of map view frame, type 10,000 in the Scale textbox, then click on the Go button. This will zoom the map out to a wider (smaller scale) view. 5. Click on More Tools in the tool bar on the right-hand side of the MapView frame to open the More tools toolset and click on Buffer Selections. 6. In the first Find dropdown, select Known Contaminated Sites List. Use the Near a point on map option, and enter 0.5 miles as the Within buffer radius. Then click on the red cross symbol on the map that represents your home or other address located. The application will find any Known Contaminated Sites within a 1/2-mile distance from the location clicked on the map, and the map view will zoom to the extent of the buffered area (purple lined circle). The Known Contaminated Sites within the buffered area will be highlighted and (up to) the first 20 will be labeled. A Known Contaminated Sites List selection list will be added to the Results window at the bottom and the reference numbers will correspond to the labels on the map. 7. The total number of records retrieved will be listed in the title row of the Results table, next to the layer name. To see the next 20 selected records, scroll to the top right of the Results table for Known Contaminated Sites List and click on the page 2 tab. 8. Click on More Tools to open the More Tools toolset. Click on the Measure tool to use it to determine the distance from your home (or other address located) to the nearest Known Contaminated Sites. At the bottom of the Measure Tool s window there are a number of measure tools. Select the Measure Distance tool, then mouse click on your home (red cross) and then move the mouse to the locations of the nearest sites (blue circles). As you move to each site, the distance in feet is displayed in the tool window under Geometry and also at the bottom of the map frame. Click the mouse again at one of the sites to complete a measurement. When finished close the Measure Tool window. Note: Having a Known Contaminated Site close by is not that unusual especially in a highly developed area like an urban city. Organizations like NJDEP work with local officials and private clean-up companies to minimize risks to the residents that live close by. Known Contaminated Sites represent sites where there has been, or there is suspected to have been a discharge of contamination that has negatively impacted the soil or groundwater in the immediate vicinity. These are sites where remediation (clean-up or protection controls) is either currently under way, required but not yet initiated, or has been completed. Some of these sites may have been fully remediated pg. 19

22 and should no longer be listed as known contaminated sites. 9. Zoom in to one of the labeled Known Contaminated Sites using the Zoom In tool. You can either scroll your mouse-wheel up with the cursor on the site, or drag a rectangle around the site to perform the Zoom In. 10. Find the corresponding label number in the Results Table window, and click on the Tools Dropdown and select the balloon Show On Map menu item. This will display a call out with some basic information about the site. For more information on the site and to view the additional attribute data, click on the map label number (blue) hyperlink under the Info column. This brings up the More Information box. 11. Scroll down within the More Information box and click the Print button. Select the Portrait Web Print, option, then enter a title, sub-title, and select HTML as the output format (you can select PDF if you have Adobe Reader installed on your PC). Experiment with the map preview by checking and un-checking the Retain Scale checkbox. Click on the Print button if you want to print the map. Click Cancel to close the Print window and return to the map view. Close the More Information widow. 12. Clearing Selections. To clear the selected features for the Known Contaminated Sites List layer only, click on the X next to the Known Contaminated Sites Layer Tab. To clear selection lists from the entire Results table, click on the X in the very top row, right corner of the results table called Close Clear Results. A window will pop up confirming your action. Click OK to clear the selections 13. Scroll to the top, and mouse-over the Searches drop down. Select the Watershed/Sub- Watershed search to search for a sub-watershed (HUC14). By selecting from the preceding dropdowns (Watershed Management Area then Watershed) the values the for Sub- Watershed dropdown list is limited by the watershed designation. Select a Watershed Management Area, a Watershed, and then a Sub-Watershed then click the Search button. The map will zoom to the sub-watershed and a sub-watershed record will be added to the Results window. Ex: Lower Raritan, South River, and Lawrence; Matchaponix Brook; Barclay Brook. pg. 20

23 14. Note that the data within the Results table can be exported or saved using the various reports that are available at the top of the selected set under the Reports drop down. The data can be exported as CSV files, HTML files, PDF and XML files. For some layers, you may find additional custom reports added to this dropdown. Clicking on the hyperlinked number next to each item of the selection will provide attribute information for that item. More tools are available when the More Tools button is clicked. This will open another menu with a scroll bar, that displays additional functions. (These are described on page 14) Notice that the Watershed/Sub-Watershed Search is minimized below the You can re-open this search by clicking on the window by clicking on the X (Close) button Home button. Expand button or remove this search 15. From the Map Tools toolbar, click on the Overview Map tool on the lower right-handside of the map view frame, to open the overview map. See where the sub-watershed lies within New Jersey. 16. In Map Content Window, scroll to the Environmental Monitoring layer group and check on AMNET Biological Monitoring Sites. The layer will draw on the map, featuring water monitoring sites as colored star symbols. 17. Look for any AMNET Biological Monitoring Site points that are red or orange stars (these denote severe or moderate biological impairment the water is not clean enough for a wide diversity of fish and other organisms to live there). Use the Zoom In tool (Map Tools toolbar) to zoom in to a smaller area surrounding one of these points by drawing a square around the point. The resulting scale should be a map scale larger than 1:25,000 (i.e. 1:10,000). If it is not, type the scale number in the scale text box in the lower left corner of the map view frame, and click on the Go button. Now click on the center of the Navigation Bar Control to zoom to the full extent of the map. Notice the overview map changes to show the new map extent (a larger red rectangle around the whole map of NJ). Use the Previous Map Tool to view the previous maps until you get to one which is close to a scale of 1: Click on the Overview Map tool once again to hide the overview map. 18. In the Map Content window, scroll down to the Water layer group, and check on Streams and Water Bodies. Within the Sites and Facilities layer group, check on NJEMS Sites. NJEMS Sites are sites that programs within NJDEP have an interest due to the activities pg. 21

24 that occur at these facilities. These sites often are required to get environmental permits and many must be routinely inspected by NJDEP staff to ensure the activities that occur at the site do not violate the rules of their permits. 19. In the Map Content window, scroll to the Land layer group, and click on Land Use From the Map Content toolbar, click the Legend button to open the legend window. Notice which symbols represent which layers. Click back to Layers. 21. Industrial pollution sources, storm water runoff, as well as land use activities are likely impacting the biological communities the fish and other living things in the streams here. From the Map Tools toolbar, click on the Identify tool, and then click on a Land Use polygon near the Ambient Biomonitoring Network point. In the More Information window click on the Attribute Details For dropdown and select Land Use Click on several surrounding Land Use 2012 polygons. Do the same for any NJEMS Sites features by first changing the Attribute Details For dropdown to NJEMS Sites then using the Identify tool. The information displayed provides the location of the site and the NJDEP program(s) that have interests at the site. When finished, close the More Information window, and go to the Map Content window and turn off the Land Use 2012 layer. 22. After identifying a feature from the NJEMS Sites layer, scroll to the bottom of the More Information window and expand the Documents list by clicking on the sign. Click on the document link to access Program Interests by Site ID Data Miner Reports. The resulting page will display NJDEP program interests for this site. After viewing, close the Data Miner application window and the More Information window. 23. Mouse-over the Searches link. Click on the NJEMS Site search. Enter as the Preferred ID Number (Pref Id Num). Make sure Program (Description) is blank and click on the Search button. The application zooms to the site, and the NJEMS site record is added to the Results window. 24. Click on More Tools to open the More tools toolset and click on Buffer Selections. 25. In the Buffer Selections window, select Streams as the Target Layer in the Find drop down, and enter 2000 feet as the buffer radius under Within:, and select the Near currently selected option. Select NJEMS Sites from the dropdown list and click the Search button and the buffer will draw. The application will find Streams within 2000 feet of the NJEMS Site. The Streams will be highlighted and labeled. A Streams selection list will be added- to the Results window and the reference numbers (hyperlinks) will correspond to the labels on the map. On the Results table s More Tools menu click on the Zoom to All tool to see the full extent of the selected streams. pg. 22

25 26. To clear the selections click on the red X in the Streams results within the Results table. A window comes up asking you to confirm. Click OK. This will clear the selection but the Buffer remains on the map. To delete the graphic of the buffer, click on the Clear Buffer Rings tool within the More Tools toolset. The Buffer Ring will disappear. 27. Close out of NJ-GeoWeb. End of Tutorial 1 pg. 23

Select several counties from the dropdown menu by either holding down the Shift key and/or the Ctrl key. Click on the Show Selected hyperlink to show the counties you just selected in a list box then click on the Search button. The selected counties will be highlighted on the map, and a Results window will open and list the counties selected along with some attribute data. The labels on the map correspond to the blue hyperlink index numbers in the Results List. pg. 24

27 10. As a result of this search, the Results tab has now appeared below the Map. The information displayed on the Results tab page is additional attribute data coming from the County GIS layer. Uncheck one or more of the checkboxes that correspond to some of the counties, and then click on the Zoom To Selected Tool in the Results table. The map refreshes and zooms to the extent of those counties whose checkboxes remained checked. The Results tab can be used to further refine a selection. 11. Delete the Counties Results List by clicking on the x to clear the selected Counties results. 12. Mouse-over the Searches dropdown, and then click on the Municipality tab to run a municipality search. Select a County (Mercer) then a Municipality (Hamilton) from dropdown boxes and click on Search button. The application will zoom to the selected municipality, and a results list will be created, with a record for that municipality. Turn on the 2012 Imagery (Natural) and uncheck any previously checked Imagery above it like the 2015 Imagery (Natural). The image will be rendered in the map view. Click on the blue 1 hyperlink in the results list to get more information on the selected municipality. Close the More Information window. 13. Click inside the map Scale box, enter 15000, and then click on GO.
